I'm seeking wisdom about preferred e-commerce toolkits to use to create basic cookie-cutter e-commerce stores. I'm coming from the perspective of a website development and hosting firm. We want to offer an option to customers that is low cost, and takes less than an hour to set up for each customer.

I would love if the solution also used my favorite technologies, including HTML::Template, CGI::Application, and the Postgres database. I once tried Interchange, and found it much to cumbersome to use.

Recently, we also evaluated Web+Shop and ran into a number of issues getting it up and running for the first store. The experience made me want to look again at fully open source options.

As I look again at the remaining options, OScommerce caught my eye. It uses PHP and MySQL, but is open-source. While I'm less familiar with (and fond of) PHP, I doubt it can be any more foreign than the custom tag languages that come along with Interchange and Web+Shop.

I figure that if the data model is decent, it shouldn't be too hard to extend the application with Perl if I need to.

Before I futher evaluate OScommerce, is there a great Perl e-commerce toolkit that I've overlooked?

Thanks!
